Good Afternoon, Harry Freakstorm. You Body Order Stench Quotient has gone up 25% since your last logon. Were you:

A: In an endless Meeting with that windbag?B: Using the stairs because you are afraid the elevator doors will crush you?C: Talking to Julie in Accounting and generally making yourself look and smell even worse?

Sir. It shows, you usually use your right armpit. Are you trying to sign in under duress? Is there someone there forcing you to login? You can answer Whether for Yes or Weather for no.

What? No. I just want to logon.

C'mon, sir. Whether or weather. I can help.

No! I just need to login!

Okay sir. I assume you are not under duress and simply need access to your computer. I'm resetting the biometric sniffer to your default body odor. This is the one you set up originally. Please place your right armpit to the sniffer and press "Ready"

SpectroBoy:Yeah, because that won't change with diet, health, perfume, etc.

If you bothered reading TFA, they say that although some aspects of your BO vary, there are some markers that stay the same no matter what age you have or deodorant you're wearing. The scanner is looking for those markers.

The researchers claim their studies show these patterns can be detected with an 85% accuracy rate. That's higher than the rates for facial recognition and some forms of eye scanning.

That's BS. Except if the development of your facial recognition sw ended in the last century.

Also, methods of biometric identifications are the "who you are", passwords are the "what you know" factors in authentication. They are not interchangeable. They should be used in combination for best security. See Link
